Before:
  .k-treeview-top { border-top: 1px solid; }
  .k-treeview-mid { ... }
  .k-treeview-bot { border-bottom: 1px solid; }

After:
  .k-treeview-item-content { border-top: 1px solid; }
  .k-treeview-item-content { ... }
  .k-treeview-item-content { border-bottom: 1px solid; }

Also, the .k-treeview-leaf selector for state classes (.k-hover, .k-focus, .k-selected, .k-disabled) is replaced with .k-treeview-item-content.`;
